the opacity less marked medially and more broadly basally (9), 

 the second stria with a puncture at three-fifths (cf ), which is wholly 

 obsolete in the single female at hand; abdomen with fine sparse 

 punctures behind the coxae. Length (cf 9 ) 13.0-13.5 mm.; width 

 4.5-5.0 mm. Illinois viduus Lee. 



4 Body rather large in size, the head very large. Color deep black, 

 shining, the elytra (9) sericeo-opaque; anterior and middle tarsi 

 paler; head three-fourths (cf) to nearly four-fifths ( 9 ) as wide as 

 the prothorax, the eyes relatively rather small and prominent, the 

 foveae minute, punctiform ; antennae testaceous, blackish toward base, 

 slender; prothorax one-half wider than long, as in viduus, except that 

 the broadly convex surface between the large linear, broadly and 

 deeply impressed punctate foveae and the sides is irregularly and 

 sparsely strewn with very fine feeble punctulation; basal margin 

 differing in not being interrupted medially; elytra nearly two-thirds 

 longer than wide, evidently wider than the prothorax, with rounded 

 sides, which arcuately converge to the ogival apex from only slightly 

 behind the middle, the sinus very feeble but evident; striae (cf) 

 rather fine, deeply impressed, with broadly convex polished inter- 

 vals, or ( 9 ) very fine, superficial, with perfectly flat opaque in- 

 tervals, the scutellar stria long, the puncture at the second stria 

 near apical third impressed and distinct (cf ), or very small and feeble 

 ( 9 ) ; abdomen with the post-coxal punctures fine and sparse, asperu- 

 late as usual. Length (cf 9 ) 13.8-14.8 mm. ; width 5.5-5.7 mm. 

 Michigan (Whitefish Point Schwarz) and Wisconsin (Bayfield 

 Wickham) laticeps Lee. 



Body rather large in size, the head moderately large. Body oblong- 

 suboval, more strongly convex than in laticeps, deep black throughout 

 when mature, the abdomen sometimes rufescent; lustre polished, 

 the elytra sericeo-opaque in the female; legs as in laticeps; head 

 three-fifths to two-thirds as wide as the prothorax, relatively a little 

 larger in the female, the eyes moderate and prominent; antennae 

 slender, testaceous, darker through most of the three basal joints as 

 a rule; prothorax one-half wider than long, only very slightly (cf ) 

 or much ( 9 ) narrower than the elytra, nearly as in laticeps through- 

 out, the basal angles but slightly obtuse though narrowly rounded 

 as usual, the foveae a little shorter and not quite so deep, the punctures 

 on the broadly and feebly convex surface thence to the sides very 

 fine, sparse and feeble; elytra oblong, one-half ( 9 ) to three-fifths 

 (cf ) longer than wide, the striation and intervals in both sexes very 

 much as in laticeps, the dorsal puncture also similar; apical sinus 

 very feeble though evident; sutural angles ( 9 ) minutely denticulate; 

 fine post-coxal punctures of the abdomen forming only a small 

 patch, the terminal setae two at each side in both sexes as usual; 

 legs rather short, the tarsi unusually abbreviated, the posterior 

 (cf ) only about two-thirds as long as the tibiae, polished and smooth 

 throughout above, the basal joint slightly longer than the fifth. 

 Length (cf 9 ) 12.8-14.0 mm.; width 5.0-5.6 mm. Colorado.
